Fan powered box room temperature control heating (FpbTRCtlH11)

Overview

The application function "Fan-powered VAV box room temperature control for heating 11" (FpbTRCtlH11) is the hub for the sequencing of the room temperature controllers for FPB heating. It determines the room heating setpoint and the room heating demand signals to maintain the room temperature at the heating setpoint.

The following devices in the room segment(s) are supported:

Heating coil
Radiator
Heating/Chilled ceiling
Heating/Cooling coil
Supply air VAV damper
Fan

Function

This AF works in collaboration with a room segment HVAC device component heating AF. The heating room temperature PID controller is enabled based on a signal that is read via the grouping function (from equipment in the room segment) indicating whether heating is available.

Devices for heating are activated in the following order (default):
Radiator > Heated ceiling > Heating/Cooling coil > Heating coil > Fan > VAV

Parameters

Description	Parameter	Default value
Fan operation 0:Series 1:Parallel ▶ Parallel means Fan speed is influenced by valve position.	FanOp	1:Parallel
Coil valve start position by parallel operation	CoilVlvSttPrl	10 [%]
Coil valve end position by parallel operation	CoilVlvEndPrl	100 [%]
Fan end speed by parallel operation ▶ These values are related to the demand signal, the actual setpoint for the speed depends on the settings in the segment.	FanEndSpdPrl	50 [%]
Comfort configuration 1:None ▶ None, means no aggregate is activated depending on heating demand. 2:Radiant devices ▶ Radiant device, means only radiant devices (e.g. Radiator) will be activated depending on heating demand. 3:Air treatment devices ▶ Air treatment devices, means only air treatment devices (Heating coil, Fan) will be activated depending on heating demand. 4:Radiant & air treatment devices ▶ Radiant & air treatment devices, both will be activated depending on heating demand.
